Solving Systems of Equations by subtraction
Please solve this

Step-by-step explanation:

We can subtract the first equation from the second to find the value of , although we can also do this vice versa.

Now, we can use substitution to solve for :

(pick any equation for substitution)

Hope this helps :)

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
